Embodiment 1

[0124]

[0125] (Purpose)

[0126] A fiber-reinforced composite material was produced and its physical properties were verified by fabricating a non-woven fabric made of a bag moth larva spun silk as a reinforcing fiber.

[0127] (method)

[0128] As the bag moth larvae, the larvae (body length 10-15 mm) of the bag moth collected at a fruit tree farm in Tsukuba-shi, Ibaraki Prefecture were used.

[0129] The nonwoven fabric of silk thread of bag moth larvae was obtained by the following method. About 50 bag moth larvae were put into a cube-shaped rearing cage with a vertical and horizontal height of about 20 cm, and raised for 7 days. The upper top plate of the breeding cage is made of acrylic resin and can be attached and detached. Bag moth larvae have the property of moving upward, so the stay time on the back side of the cage roof becomes longer. As a result, a large number of bag moth larvae continued spinning disorderly on the back surface of the top plate, and afte...

Abstract

The present invention addresses the problem of developing and providing a fiber-reinforced composite that contains bagworm moth silk threads as reinforcing fibers, and is isotropic in terms of elastic modulus and strength. Provided is a fiber-reinforced composite containing, as reinforcing fibers, a nonwoven fabric comprising bagworm moth silk threads.

Description

technical field [0001] The present invention relates to a fiber-reinforced composite material comprising a nonwoven fabric containing spun silk of bag moth larvae as reinforcing fibers and a method for producing the same. Background technique [0002] Fiber-reinforced composite materials composed of reinforcing fibers and base materials, such as carbon fiber-reinforced plastics (CFRP: Carbon Fiber-Reinforced Plastics) and glass fiber-reinforced plastics (GFRP: Glass Fiber-Reinforced Plastics), are Lightweight material with high strength and modulus of elasticity. Such high strength and elastic modulus are largely based on the mechanical properties of reinforcing fibers such as carbon fibers, glass fibers, and aramid fibers. For example, carbon fiber is known to have mechanical properties about 10 times that of iron in terms of specific strength obtained by dividing the strength by the mass of the raw material (Non-Patent Document 1). Due to such mechanical properties, fibe...
