Strength of Selected Methods for Joining Low-Density Fiberboard

Fiberboard panels of 35 and 42 pounds per cubic foot density were made from pressure-refined fiber from total tree hardwood chips. Face and edge withdrawal tests of wood screws and threaded metal inserts were conducted with and without poly vinyl acetate glue in the lead holes. Various joining techniques were simulated with box-type specimens made with dowels, dovetails, wood screws, or metal inserts and tested in tension. The glue improved the withdrawal resistance of the wood screws and inserts. The highest loads were obtained with the dowels and inserts; wood screws produced much weaker joints. With choice of the proper fastener and careful design, satisfactory joints in 35-pcf fiberboard are possible.
