Light thermoplastic honeycomb plate composite material tray and manufacturing method thereof

Abstract

The invention discloses a light thermoplastic honeycomb plate composite material tray which is formed by a honeycomb plate panel and a plastic support column through contact surface bonding or welding; from the structure, a thermoplastic honeycomb is taken as a core material, so that tray weight is greatly relieved, elasticity and compression resistance are improved; and a surface layer adopts a continuous fiber reinforced thermoplastic material, so that impact resistance and puncture resistance of the tray are greatly improved. An inverted tower shaped plastic support column structure is adopted, so that the bottom of the plastic support column tilts inwards, and frequent collision during carrying is avoided; and a hollow-out structure is adopted inside the plastic support column, so thattrays are stacked together to save space, the contact area between the plastic support column and the honeycomb plate panel accounts about 20%-30% of the total area of the honeycomb plate area, and bearing ability and bending strength of the panel are strengthened.

Description

technical field [0001] The application relates to a light-weight thermoplastic honeycomb board composite material tray and a manufacturing method thereof, which are mainly applicable to the design and manufacture of the tray. Background technique [0002] As pallets for storage, stacking and handling of goods, wooden pallets, metal pallets and plastic injection pallets are mainly used at present. Wooden pallets are usually used for storage and transportation of goods all over the world. Each of these pallets has a number of disadvantages. For example: wooden pallets, which are limited in load capacity; easily damaged or cracked; absorb moisture, liquids and odors; can be contaminated by termites and insects; Metal pallets are expensive to manufacture and heavy in weight; they are prone to rust in humid and acid-base environments. Plastic injection trays have low strength, limited carrying capacity, poor impact resistance, and short service life. Contents of the inventio...
