Composite Sandwich Core Fabrication

Consists of low strength facings or skins, being adhesively bonded to the high density core

Consists of high strength facings or skins, being adhesively bonded to the low density core

Consists of fibreglass core and being adhesively with epoxy resin

Usually low density material

Place in the middle of a sandwich construction

Required high strength of core material

The outermost layer, generally thin and of high density.

The central layer, generally thick and of low density,

The outer layer of composite, generally low strength of material.

To bind the core and the facing

To bind the fibre

To glue the core and the fibre

Core Template Transplant

Core Trim Template

Core Testing Template

Sanding the burr by sand paper

Cutting the burr by using knife

Blowing the burr by pressure air

To remove moisture on the core surfaces

To reduce dust on the core

To avoid damage on the core

To smooth the core selection process

To enhance the strength of the core

To avoid the core from damage

To lower the strength on the sandwich composite

To avoid damage on the core in sandwich construction

To minimize the defect during laminating sandwich construction

PPE is stands for Personal Protective Equipment

Google is one type of PPE

Brush and cotton rag is use as PPE during laminating process
